[Tinycc-devel] Speed?

REHI

I started to look at src code and I saw this in i386-gen.c:

/* XXX: make it faster? */
I think it is a TODO

And after the code:

void o(int c)
{
        while (c) {
                g(c);
                c = c / 256;
        }
}

Correct me if I'm wrong, but isn't shift faster than division?

If so, the line

        c >>= 8;

Should be faster than

        c = c / 256;

That's what I've seen by now... I'll keep surfing ;)
